Why Choose the ABB M3SS5-20U Selector Switch?
The ABB M3SS5-20U is a three-position momentary selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular plastic pilot-device range, it features a grey long-handle rotary actuator with a chrome-plastic bezel for clear and convenient operator control.
The M3SS5-20U provides positions A, B and C with spring return from A to B and from C to B. Both outer positions are momentary, so releasing the handle automatically returns the selector to its centre B position, making it particularly suitable for temporary directional, jogging and machine-command functions.
Designed for ABB's modular operator system, the M3SS5-20U is a non-illuminated selector-switch operator supplied without a contact block. Compatible ABB modular contact components can therefore be selected according to the switching arrangement required by the application.
Key Advantages
- Three-position momentary operation provides temporary commands in either direction.
- Spring return from A and C to B automatically restores the selector to its centre position when released.
- Grey long-handle actuator provides convenient rotary operation.
- Chrome-plastic bezel provides a clean industrial operator interface.
- Non-illuminated design suits applications where visual illumination is not required.
- Modular ABB construction allows compatible contact blocks to be selected for the required control circuit.
- Suitable for directional, jogging and temporary machine-control commands.

Reliable Momentary Control for Industrial Machinery
Three-position momentary selector switches provide temporary operator commands while automatically returning to a defined centre position. The ABB M3SS5-20U uses spring return from both A and C to position B, making it suitable for applications where either outer command should remain active only while the operator deliberately holds the selector.
The M3SS5-20U forms part of ABB's modular pilot-device system, allowing machine builders and panel designers to configure the operator with compatible contact blocks for the required control logic. Its grey long handle and chrome-plastic bezel provide a clearly identifiable and practical interface for industrial machinery and automation equipment.
Typical Applications
- Industrial machinery control panels.
- Forward / centre / reverse momentary commands.
- Raise / neutral / lower control functions.
- Jogging and machine-positioning controls.
- Manufacturing and production equipment.
- Material handling and conveyor systems.
- OEM machinery and industrial automation systems.
